Miltiades the Younger (c. 550 BCE – 489 BCE) or Miltiades IV, is the son of one Cimon, a renowned Olympic chariot-racer.

Miltiades considers himself a member of the Aeacidae, and he is a member of the prominent Philaid clan.

He is known mostly for his role in the Battle of Marathon; as well as his rather tragic downfall afterwards.

His son Cimon was a major Athenian figure of the 470s and 460s BCE.

His daughter Elpinice is remembered for her confrontations with Pericles, as recorded by Plutarch.

Named after his uncle, Miltiades the Elder, the junior Miltiades is best known for his victory over the Persians at Marathon.

The Philaid dynasty was continued by his son, Cimon the Younger.

The name "Miltiades" derives from miltos, a red ochre clay used as paint.

It was a name often given to red-haired babies.
